long) ; leaflets entire, obcordate, glabrous, except foi- a few 

 scales, jointed to petiole, cuneate at base; apex emarginate or 

 retuse, with sometimes a slight mucro in the centre of the 

 sinus. 



3rd leaf similar to those described, but not yet fully de- 

 veloped at time of writing. 



As the development of the seedlings under examination is 

 not yet far enough advanced, I have reserved comparison with 

 mature form for future occasion. 



No. 514 Ozothamnus depressus, Hook, f. Plate XXXIV., 

 figs. 50 and 51. 



Seed collected from plant growing on stony bed of River 

 Kowai. Germinated in about* four weeks. The seed germi- 

 nates very freely, but it is difficult to keep the young plants 

 alive for any lengthy period. 



Description of Seedling. 



Hypocotyle at first succulent, very early on becomes 

 woody, and is already 4 mm. long, as the tip of the first leaf 

 can just be seen arising from between the cotyledons. 



Cotyledons (Plate XXXIV., fig. 51) 2 mm. long, broadly 

 oblong, obovate, almost obcordate at times, sometimes un- 

 equal in size, emarginate, obtuse, retuse or truncate, indis- 

 tinctly pubescent with very short white hairs, sessile, amplexi- 

 caul, at first erect protecting the 1st leaf, then becoming more 

 patent. 



1st pair of leaves (Plate XXXIV., fig. 50) 2-5 mm. long, 

 linear-oblong to linear-spathulate, amplexicaul, very succulent, 

 densely woolly with long matted hairs which are erect and 

 adpressed to stem below, patent above, with apex curving 

 downwards. 



2nd pair of leaves 3 mm. long, similar in other respects 

 to the 1st pair. 



Stem terete, very soft and succulent, very pale-green, 

 woolly but not so much as the leaves ; 1st internode 1'5 nun. 

 long; 2nd internode 2 mm. ; or the internodes may be almost 

 suppressed or very indistinctly seen, owing to the leaves being 

 so closely adpressed to the stem. Before the opposite leaves 

 open out their hairs are all matted together into one mass. 



In the mature plant the leaves are most closely adpressed 

 with ventral surface to stem, and covered, as in seedling, with 

 dense matted cotton ; the dorsal surface, also equally tomen- 

 tose in the seedling, is in the adult covered with a silky 

 pellicle, and the internodes are almost suppressed. Plants 

 cultivated in a shade-house have put forth shoots with ad- 

 pressed leaves, but green on the dorsal surface, much less
